Phys.org / Mars mission simulations reveal key to teamwork under pressure
Whether it's to the moon or Mars, a NASA mission requires some essential preparations: designing and developing the spacecraft, astronaut training and safety checks, clear goals, and strategies and procedures for maintaining ...
Phys.org / Atlantic and Pacific may follow different rules on long-term warming, analysis shows
Florida State University researchers have identified key differences in the root causes of long-term sea-surface temperature changes across the Atlantic and Pacific oceans, a finding that could help guide future research ...
Medical Xpress / Colorectal tumors use mitochondrial complex II to stockpile iron, but eliminating it causes cell death
Scientists know that colorectal cancer cells require large amounts of iron and that as cancer becomes more aggressive, the cells have even higher amounts of iron. Normal cells with high levels of iron would undergo a type ...
Medical Xpress / Pakistani genomes reveal 34,000 knockouts that could explain why mouse-based drugs fail in humans
A comprehensive analysis of 173,303 genomes from Pakistan, published today in Nature, is upending how scientists understand human genetics and drug development. By identifying 34,000 people who are "human knockouts," with ...
Medical Xpress / Rewired metabolism helps revive exhausted immune cells and boost cancer immunity
Researchers from National Taiwan University (NTU) and National Taiwan University Hospital (NTUH) have identified a promising way to reinvigorate the body's cancer-fighting immune cells by rewiring their metabolism, revealing ...
Medical Xpress / How intermittent fasting may shield the brain from chronic stress
Chronic stress, the prolonged exposure to psychological and/or physical strain, is known to be a risk factor for depression, anxiety and some other psychiatric disorders. Past studies suggest that chronic stress disrupts ...
Tech Xplore / Electric 'nose' can smell when your food's gone bad
Most of us have used the sniff test to decide whether a slightly expired bottle of milk or a week-old box of takeout is still good to eat. But while the human nose can be quite astute, it doesn't always catch everything. ...
Phys.org / Dozens of active dust devils caught swirling across Mars canyon system
The European Space Agency's Mars Express has captured part of Mars's Mamers Valles, a fascinating valley system speckled with brief, tornado-like whirlwinds known as dust devils.
Phys.org / Drug-free nanoparticles stop tumor growth by transmitting biological messages to immune cells
A research team from the Technion's Wolfson Faculty of Chemical Engineering has developed an original technology for treating cancer using nanoparticles that carry no drugs at all and has demonstrated its effectiveness against ...
Phys.org / Mountain lions have major ecological impact even in small preserves
Big cats have a big impact. A long-term study showed that when mountain lions began regular visits to a small suburban preserve about 45 miles (72 kilometers) south of San Francisco, they changed the behavior of many other ...
Science X / Most people accurately read their partner's insecurities, but misreads might actually do some good
Identifying one's partner's emotional needs plays a foundational role in romantic relationships. Most people think they actually have a pretty solid understanding of their partner's attachment style and often actively behave ...
Phys.org / Super El Niños may lose their punch in a warming world
In a strong El Niño winter, normally dry regions can suddenly drown in rain. NASA notes that "typically dry regions can experience nearly two times as much rain during a strong El Niño." Indeed, the blockbuster El Niños of ...
